Be ready to serve Jesus day and night, Luke 12:35-40

Having yourself ready for the master day or night.
Master, in this case is Jesus.

The lamp represents the light of God and his son Jesus.
JESUS IS THE LAMP AND GOD IS THE LIGHT.

The Watchful Servants – The Lamp

12:35“You must keep your belts fastened and your lamps burning. 36 Be like people who are waiting for their master to return from a wedding. As soon as he arrives and knocks, they will open the door for him. 37 How blessed are those servants whom the master finds watching for him when he comes! I tell all of you with certainty, he himself will put on an apron, make them sit down at the table, and go around and serve them. 38 How blessed they will be if their master comes in the middle of the night or near dawn and finds them awake! 39 But be sure of this: if the homeowner had known at what time the thief were coming, he would have watched and would not have let his house be broken into. 40 So be ready, because the Son of Man is coming at a time when you don’t expect him.”Luke 12:35-40
